Shear Instability Jet

Research at the laboratory investigates thermal and fluid transport phenomena at various length scales in multiphase systems. Thermal transport in energy systems is often governed by the transport phenomena at interfaces, and controlling interface properties and documenting their effect is vital to improving device efficiency. We use a variety of experimental techniques towards exploring the fundamental limits to thermal transport, and enhancing fluidic mixing. Systems investigated include heat transfer in solid-gas flows with complex geometry, liqui-vapor phase change heat transfer in boiling and thin film evaporation, and heat transfer in turbulent boundary layers. We are also interested in using flow instabilities for enhancing energy efficiency in fluid mixing and atomization processes. The research has a variety of applications such as heat exchangers and boilers in thermal power plants, electronics cooling, food and materials processing to diesel exhaust remediation.
